ive decided to mini tub my nova and ive found that the wheel base i need happens to be the dimensions of a 93-94 s-10. the length of the housing should be just perfect to fit my 11'' wide rims back there. the 4.3L V6's with 5 speed manuals have 8.5'' rears with POSI's. do you think these will hold up to the 425+hp the nova is running?
